hdl-util / mipi-demo Goto Github PK

Hi @sameer,

Thank you for sharing all your work. I find it very helpful and i learn a lot from it.
I saw you mentioned that there is support for imx219 driver at https://github.com/hdl-util/mipi-ccs.
May i know if imx219 driver is working? I tried it but it doesn't seems to show anything from the camera except arduino logo.

I swapped the ov5647 module to imx219 as below:
imx219 #(.INPUT_CLK_RATE(48_000_000), .TARGET_SCL_RATE(100_000)) imx219 (
.clk_in(CLK_48MHZ),
.scl(MIPI_SCL),
.sda(MIPI_SDA),
.mode(mode),
.resolution(resolution),
.format(format),
.ready(ready),
.power_enable(MIPI_GP[0]),
.model_err(model_err),
.nack_err(nack_err)
);

Beside that there is some timing violations during synthesis not sure if this is a problem.

Hi,

thank you for all your work and samples it helped a lot to get some results with my board!

I am using most of your files with my ECP5 CM4 IO compatible board, and I am now able to get stable picture.
But I get 16 pictures and I can see that at least two are different.
Maybe you had something similar and could point me to solution?

I am using ov5647 raspberry cam rev 1.3

Here is better picture with timer

Hi @sameer,

Firstly, thank you for doing all this work to get a working mipi-hdmi interface on the mkr vidor. I'm new to FPGA's and have been using this board to test some basic logic gate examples. Up until now, I've been using the method shown here to simultaneously upload SAMD21 code as well as the bit file to the FPGA.
I would love to implement and demo your code, and ultimately try to save image frames to an SD card. Having reviewed the files in your repository, I was wondering if the prior method could be used, or if another method is required?
Additionally, I am unfamiliar with HDLmake, is this tool also necessary for compiling?
I apologize for this basic implementation question, any help would be greatly appreciated.

Thanks!
